Title: Method for preparing virus antigen
Inventor: TOUGI AKIKO
IPC: C07K14/01
Filed: 1999-09-27
Abstract: PROBLEM TO BE SOLVED: To acquire a virus antigen having an enhanced antigen activity by reaching a peptidyl prolyl cis-trans isomerase(PPI ase) with the virus angigen. SOLUTION: A PPI ase prepared from an eucaryote, an eubacterium or an old bacterium is used. As an encaryote origin, a cyclophilin originated from a pig or the like is used. As an eubacterium origin, that originated from a colibacillus is used. As an old bacterium, that originated from a sulfolobus genus or the like is used. The virus antigen for reaching these PPI ase is, for example, diluted with a phosphate buffer solution. Its ion strength preferably includes NaCl of 0.05 to 1 M, and the virus antigen of suitable amount is added to a virus antigen liquid. In the reaction of the virus antigen liquid with the PPI ase, they are mixed so that the PPI ase becomes about 0.01 to 200 times as large as the virus antigen by a molar ratio, and used.  If the PPI ase is less than 0.01 times, sufficient reaction cannot be obtained or if it is more than 200 times, there is possibility of bringing about a side reaction. Thus, about 0.05 to 50 times is preferred.

Title: Magnetic head device
Inventor: SHIMIZU TAKAO
IPC: G11B5/127
Filed: 1988-10-31
Abstract: PURPOSE:To attain high density recording by setting the effective cross section area of each edge part facing the magnetic recording medium of a magnetic flux guide at a small value, and applying a superconducting member around each edge part of the magnetic flux guide. CONSTITUTION:A magnetism recording means 1 and a magnetic flux guide 2 to guide a magnetic signal outputted from the magnetism generating means 1 to a magnetic recording medium 10 are provided. The effective area of the part facing the magnetic recording medium 10 of the magnetic flux guide 2 is set at the small value, and the superconducting member is applied to each edge part periphery of the magnetic flux guide 2. Consequently, when the superconducting member in the external periphery of the magnetic flux guide 2 is in a superconducting condition, since the magnetic flux guide 2 expresses complete diamagnetism, the magnetic flux generated by the magnetic field generator 1 does not leak out of the magnetic flux guide, and it is guided so as to pass through one edge part 2A, the magnetic recording medium 10, and the other edge part 2B in the magnetic flux guide 2. Thus, the magnetic flux at the comparatively high density is formed in the part facing the magnetic recording medium 10, and the high density magnetic recording is attained.

Abstract: PURPOSE: To cut the crystalline lens of an eye by a flexible wire in the posterior chamber of the eye, by inserting a surgical apparatus with a handle supported by an operator into the anterior chamber of the eye and then moving an actuator rearward to back a flexible wire into a tubular member. CONSTITUTION: An actuator 40 is set to a retreating position to insert this surgical apparatus through a section part. Then the actuator 40 is moved to a forwarding position so as to form a ring 44 on a plane almost parallel to the plane of the nucleus 70 in an eye 70. To cut off the nucleus 70, the ring 44 is rotated through the cortex 78 so as to make the nucleus 76 be partially surround by a wire 34. The ring 44 is turned by turning a handle 12 of the surgical apparatus 10. By backing the actuator 40 to back the wire 34, the nucleus 76 is cut off by the wire 34. Consequently a first cut part 92 about 1/3 of the nucleus 76 can be formed by using the surgical apparatus 10. To form a second cut part of the nucleus 76, the wire 34 is extended again by moving the actuator 40.
